Description

The server stops and starts and I believe is the reason I am not seeing my activation code for signing up a user.

output:

Possible Solutions

Restarted mac and terminals and now I get the email for signup. Not sure what the issue was but the server seems steady now.

Re-opening this issue. The app works and then it does not. Same error as far as I can tell.

The above exception (server closed the connection unexpectedly

If anyone can help resolve...

site-packages/psycopg2/__init__.py", line 127, in connect

seems to be the issue. Line 127 is this:

conn = _connect(dsn, connection_factory=connection_factory, **kwasync)

I have googled around for a hint but no solutions. The weird / hard issue is that the server connects and works for a little bit. But then just stops. I re-did the setup twice and the issue shows up in 18.6 when you run the server for the first time on the everycheese project.

The pg_isready return:
/tmp:5432 - accepting connections
So the db is ready.

I did notice the book shows the directory as::
/var/run /postgresql: 5432 accepting connections
and mine is '/tmp: could this be a hint?
